Why is the fuel consumption of the new LaCrosse high?
1 Answers
The reason for the high fuel consumption of the LaCrosse may be severe carbon deposits or poor fuel quality, which can lead to increased carbon buildup inside the engine. Reasons for high car fuel consumption: Ignition system: The high-voltage coil and spark plugs are common faults. A faulty high-voltage coil can cause the ignition system to malfunction, resulting in cylinder misfires, reduced power, and increased fuel consumption. Oxygen sensor: The oxygen sensor is located in the vehicle's exhaust pipe and is a ceramic component that detects and controls the oxygen-to-fuel ratio. The oxygen sensor monitors exhaust gases to regulate the fuel injection system. If the oxygen sensor fails, it will affect the fuel supply, leading to a significant increase in fuel consumption. Solutions for high fuel consumption: Excessive engine carbon deposits are a major cause, primarily due to the use of unsuitable fuel. It is recommended to add a certain amount of fuel cleaner during refueling. After cleaning, it is best to drive at high speeds for a while, as this helps increase exhaust flow and allows stronger airflow to remove larger carbon deposit particles. During vehicle use, the oil filter, air filter, and fuel filter must be replaced regularly. If they are not replaced for a long time, they can become dirty and affect performance, sending incorrect information to the engine control unit, leading to incomplete fuel combustion and increased engine carbon deposits.
